When the Marvel Cinematic Universe first came to television, it wasn’t about the superheroes. Instead, it was about the group of agents just trying to do their jobs and help save the day in Agents Of S.H.I.E.L.D. Over time, the series has introduced enhanced individuals who gained their powers from experimentation with technology, and Inhumans, who were descendants of those who had Kree blood in their systems.
Though there were plans for Inhumans to get their own movie, that fell through. Instead, the royal family got their own limited series, but it didn’t get the best reactions from fans. Agents Of S.H.I.E.L.D. continued to introduce a lot of different Inhuman characters over the years, some of them more powerful than others. These Inhumans are the most powerful of the series.
Robin Hinton
The daughter of an Inhuman who could see someone’s death with just a touch, Robin becomes much more powerful than her father, though it comes with a consequence. Robin is able to see all points in time simultaneously.
She’s often called a seer, but Robin doesn’t just see the future. She also lives in and out of the past as her mind can experience everything. That being unmoored in time is part of the reason she lands at the bottom of the most powerful Inhumans. Robin being unable to tell at what point in time she even exists makes it hard for her to control her gift, and she certainly isn’t able to use it offensively.
Elena Rodriguez
Elena likes to move fast. It’s a good thing she does, because that’s exactly what her Inhuman ability involves.
Being able to move super fast does have a slight limitation for her. She can only move as far as a single heartbeat allows her to go before she snaps back into place, earning her the nickname Yoyo. Elena doesn’t rank higher on the list because her power can certainly be outmatched - especially in a fight - since her range of movement is so limited.
Gordon
Gordon is one of many Inhumans who can outmaneuver Elena thanks to his own version of traveling outside the ordinary. While she has speed, he can actually traverse space instantly. Gordon is a teleporter.
Like Elena and Robin, however, his ability certainly has an interesting limitation. Fitz and Mack are able to figure out how to use science to trap Gordon in space, eliminating his ability to even use his gift.
Abby
Abby doesn’t appear in as much of the series as some of the other characters that make the list. She has a brief arc in season five that is actually part of Jemma’s story.
One of the Inhumans forced to show off her skills in the Kree arena of the alternate future, Abby’s abilities frequently cause seizures when she struggles to control them. Jemma helps her learn to breathe through it. Her actual power involves changing her own molecular density to make her body impenetrable - or able to pass through any object. At the point the audience meets her, she doesn’t have complete control yet, but with a little work, she could be immensely powerful.
Flint
Also from the alternate future, Flint gets his inspiration from a Marvel comic book character of the same name. As that name implies, his power is centered in rocks. He’s able to manipulate any form of rock.
While in the Lighthouse, that might not give him much power since there isn’t often a lot of earth around him, it’s different when he’s in range of debris from the planet. It’s also different when he’s recreated on Earth in season six. Flint is powerful enough to reconstitute broken (and arguably magical) monoliths. His ability to combine pieces of earth was even theorized by fans to be powerful enough to put the planet back together if someone else pulled it apart.
Lincoln Campbell
The series brings Lincoln Campbell into the fold when Skye learns that she is really Daisy Johnson. He’s one of the Inhumans living in the hidden settlement called Afterlife.
Lincoln has one shocker of a power. He can channel electricity. He has enough control over it to pop his own popcorn or to light up his enemies. His range makes him a versatile fighter, though he certainly doesn’t want to be in the fight. Just how big he can go with his electrical charge isn’t clear since he sacrificed himself before we got to see the extent of his ability. If we knew exactly how much power he could channel, there’s a chance he could be higher on the list.
Katya Belakov
Katya is just a little girl when she shows up on S.H.I.E.L.D.’s radar. Her mother is an Inhuman who puts Katya through Terrigenesis to activate the little girl’s power, even though she’s advised against it.
Katya’s power is actually so great that it drives her crazy. She’s able to control literally every sensory perception someone has when she touches them. Using her ability, she controls everyone around her, leading all of the S.H.I.E.L.D. agents she interacts with to begin killing one another. If Agent May hadn’t been forced to eliminate the threat, Katya could have grown up to become one of the most powerful people in the series.
Lash
Leading off the top three most powerful Inhumans in the series is Lash. A separate personality completely from his human life of Andrew Garner, Lash’s sole purpose initially seems to be to eliminate other Inhumans.
His power pretty much involves really enormous energy blasts targeting his enemies. That energy is so powerful it can cut down his fellow Inhumans, but it can also cut through just about any substance on Earth. Lash also has a surprising ability revealed near the end of his arc: he can free Inhumans from Hive’s influence. While his energy blasts are powerful, it’s that ability to nullify Hive that really gives him his ranking.
Daisy Johnson
When she doesn’t know anything about her family, she chooses the name Skye. Once she meets them, she embraces her past - even the bad parts - and begins using her birth name.
Daisy takes a long time to really understand and use her powers properly. When she first starts to use them, she turns them inward, lessening the impact of the vibrations, but hurting herself in the process. Her power grows over the course of the few years she embraces it, and she becomes so powerful that in an alternate future she even quakes apart the planet in battle.
Hive
There’s something to be said for symmetry. The very first Inhuman ever created - the first human being to have Kree DNA given to him - is also the most powerful in the series.
Hive is functionally immortal. He can inhabit new hosts to hide his true form, so, other than being thrown into the vacuum of space, not much can kill him. That’s not his only ability. His more powerful ability involves “swaying” other Inhumans onto his side. He can make other Inhumans do anything that benefits him, which is why he ranks at the top of the list. Hive can control all of the other powers if he has those Inhumans under his sway.
